Help Please!

2007 Honda CRV running very rough. ODB2 Error code reads P0404 01/02

I have searched this data forum and googled it as well. Zero hits on this forum but a couple of hits on google - everything says it is a EGR Valve error but no where can I find where this valve is and if its something I can clean or repair.

Anyone every had this error??

Thanks

Was anything done before this happened? Do you have a voltmeter? try to unplug the connector going to the EGR valve & then test it for short to ground. Check the wiring that goes to the EGR valve see if it has been damaged or chafed . Let me know.
